The ImagickDraw::pathMoveToAbsolute() function is an inbuilt function in PHP which is used to start a new sub-path at the given coordinate using absolute coordinates. The current point then becomes the specified coordinate. This function is used for setting initial coordinates before starting drawing anything.
Syntax:
bool ImagickDraw::pathMoveToAbsolute( float $x, float $y )
Parameters:This function accepts two parameters as mentioned above and described below:
- $x: It specifies the x-coordinate.
- $y: It specifies the y-coordinate.
Return Value: This function returns TRUE on success.
Exceptions: This function throws ImagickException on error.
Below given programs illustrate the ImagickDraw::pathMoveToAbsolute() function in PHP:
Program 1:
<?php   // Create a new imagick object $imagick = new Imagick();   // Create a image on imagick object $imagick->newImage(800, 250, 'white');   // Create a new ImagickDraw object $draw = new ImagickDraw();   // Set the stroke width $draw->setStrokeWidth(30);   $draw->pathStart();   // Setting the stating point to (400, 40) $draw->pathMoveToAbsolute(400, 40);   // Setting the end point to (500, 40) $draw->pathLineToHorizontalAbsolute(500); $draw->pathFinish();   // Render the draw commands $imagick->drawImage($draw);   // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
Output:
Program 2:
<?php   // Create a new imagick object $imagick = new Imagick();    // Create a image on imagick object $imagick->newImage(800, 250, 'white');    // Create a new ImagickDraw object $draw = new ImagickDraw();    $color = ['blue', 'red', 'green'];    // Set the stroke width $draw->setStrokeWidth(5);    // Draw lines for ($x = 0; $x < 20; $x++) {     $draw->setStrokeColor($color[$x % 3]);     $draw->pathStart();     // Moving to next vertical line     $draw->pathMoveToAbsolute($x * 40, 0);     $draw->pathLineToVerticalRelative(800);     $draw->pathFinish(); } for ($x = 0; $x < 20; $x++) {     $draw->setStrokeColor($color[$x % 3]);     $draw->pathStart();     // Moving to next horizontal line     $draw->pathMoveToAbsolute(0, $x * 40);     $draw->pathLineToHorizontalRelative(800);     $draw->pathFinish();    }    // Render the draw commands $imagick->drawImage($draw);    // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
